validation: pktio: revert wait time to msec

When fixing the wait time passed to schedule by using
odp_schedule_wait_time in patch:
  commit 0bd245638dd0 ("validation: pktio: don't mix scheduler wait time and ns")

wait time was increased to 1 second instead of 1 msec
which causes the test to take nearly 2 minutes.
